Answer: 2√2 + 3√8 = 2√2 + 6√2 = 8√2 , because we simplified √8 = √(4 * 2)
Answer:
15.87 meters.
Step-by-step explanation:
We have been given a diagram of a circle and we are asked to find the length of segment YX.
We can see that line YX is tangent of our given circle and line VZ is secant of our circle.
To find the length of YX we will Tangent-Secant theorem, which states that the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment.
Using Tangent-Secant theorem we can set an equation to solve for YX as:
Let us take square root of both sides of our equation.
Therefore, the length of YX is 15.87 meters.
ANSWER
x = 4
EXPLANATION
1) 1+4x = 13+x
2) 1+3x = 13
3) 13 - 1 = 12
4) 3x = 12 (Solve for x by dividing 3 on both sides)
5) x = 4
Answer: False

Answer:
Joshua has 2a^2 -6a + 7 more than Maranda.
Step-by-step explanation:
Joshua has 6a^2 -5a + 10 dollars and Maranda has 4a^2 + a + 3 to find out how much more money Joshua has we need to subtract the amount he has by the amount of Maranda's account. Since both expressions are pollynomial we'll have to subtract the numbers wich are multiplying the same power, so we do as follow:
6a^2 - 5a + 10 - (4a^2 + a + 3)
6a^2 - 5a + 10 - 4a^2 -a -3
6a^2 - 4a^2 -5a -a + 10 -3
2a^2 -6a + 7
Joshua has 2a^2 -6a + 7 more than Maranda.
